DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The components and processing procedures of the apparatus in this embodiment are merely examples, and the present invention is not limited thereto.

1 is a block diagram showing a configuration of an image processing apparatus 100 according to an embodiment of the present invention. 1, a central processing unit (CPU) 101 controls the operation of the image processing apparatus 100 in accordance with a program stored in the ROM 102. [ The ROM 102 stores programs to be executed by the CPU 101, setting information relating to the operation of the image processing apparatus 100, and the like. The DRAM 103 is used as a temporary storage area for storing a work area of the CPU 101 and image data to be processed. Memory control such as reading, writing, and erasing of data with respect to the DRAM 103 is performed by the CPU 101. [ The operation unit 104 includes various keys operated by the user. The display unit 105 displays information to be notified to the user. The reading unit 106 optically scans the image of the original and generates image data representing the image of the original. The reading unit 106 reads the image on the original in response to the input reading instruction from the operation unit 104 after placing the original on the original table and closing the openable and closable original cover, And generates image data. The recording unit 107 records an image on a recording medium such as a printing paper using a recording agent such as ink in accordance with the inputted image data. The system bus 108 is used to perform certain data communications between components.

With the above arrangement, the image processing apparatus 100 reads the original placed on the original table by the reading unit 106, and processes each original. Specifically, the CPU 101 detects originals from image data read and acquired by the reading unit 106, extracts image data corresponding to each of the originals, and processes the image data. Further, the CPU 101 detects the tilt amount of the original, and corrects the tilt of the original. The tilt correction can be appropriately executed for a document satisfying a predetermined condition (for example, the tilt amount (angle) is 10 degrees or less). Documents that do not meet the predetermined condition are reset by the user before being read by the reading unit 106. [ Various methods can be employed as the document detection method, the document extraction method, the tilt amount detection method, and the tilt correction method.

2 is a schematic diagram showing a plurality of originals placed on the original table 201. Fig. In Fig. 2, the document table 201 is a view from above of the document table. It is assumed that the user sets the original A and the original C in a position away from the operation unit 104 and sets the original B and the original D close to the operation unit 104 as shown in Fig. The original table 201 is a transparent plate, and the image of the document set as shown in Fig. 2 is read by the reading unit 106 from the lower side of the transparent plate. Therefore, the user sets the original so that the face of the original to be read faces downward. 2, the reference line 202 extends in the horizontal direction parallel to the sides of the original table 201 extending in the horizontal direction. The tilt angle 203 indicates the tilt amount of the original. If the tilt angle 203 is equal to or larger than a predetermined angle with respect to the reference line 202, it is assumed that the CPU 101 can not perform the tilt correction. In Fig. 2, it is assumed that the original C is inclined so that the tilt correction can not be performed. The reference line 202 and the line 203 indicating the tilt angle are shown for the sake of explanation and do not exist on the original table 201. Further, the number of detectable originals is not limited to four, but a plurality of numbers can be used.

Next, a description will be given of the flow of processing for reading an image of originals placed on the original table using the reading unit 106, correcting the tilt of the image data of the original for each individual original, and processing the data separately do. Fig. 3 is a flowchart showing a process performed in this case. The flow chart shows a flow of processing performed when the CPU 101 loads a program stored in the ROM 102 into the DRAM 103 and executes the program. This flow chart is started when a manuscript copying process for extracting a manuscript and recording the manuscript on each recording medium is designated and the start of the processing is instructed by the operation unit 104. [ In this case, an operation of outputting a document after correcting the inclination of the document is designated by the operation unit 104 in advance. In addition, as for the detection of the document, the number of originals may be specified by the operation unit 104 in advance, or the number of originals may be detected automatically.

First, in step S301, the reading unit 106 reads the image of the original placed on the original table, and detects the original placed on the original table. In this case, the reading unit 106 reads a predetermined range on the original table, analyzes the image data obtained through reading, specifies the edge portion of the original, and detects the shape of each original. The document detection method is not limited to this, and various methods such as a method of detecting the document in accordance with the output of the photo interrupter provided at the lower portion of the document table when the document cover is opened and closed may be employed. Here, as shown in Fig. 2, the four originals are detected because the originals lie apart from each other.

Next, in step S302, the tilt amounts (angles) of the respective originals detected in step S301 are detected. Specifically, a rectangular area is set for each document in accordance with the shape of the document detected in step S301, and an angle formed by the lower side of the rectangle and the side (horizontal reference) extending in the horizontal direction of the document glass is detected . Here, a determination as to whether or not to perform the tilt correction process may be made, and any tilt detection method may be employed as long as the tilt correction amount can be detected to perform the tilt correction process. Further, the tilt amount may be determined by another method instead of the angle formed by the lower side of the rectangular area of the original and the lower side of the original arch base. 2, the tilt amount and the original size are specified for the originals A, B, and D. However, for the original C, the tilt amount of the original C is small It is only determined that the amount exceeds the specified amount. However, also for the original C, a rectangular area is set according to a predetermined condition. The image data of the original read by the reading unit 106 is stored in the DRAM 103 separately for each original.

In step S303, it is determined whether or not the original detected in step S301 includes the original capable of performing the inclination correction process or the original not requiring the inclination correction process (i.e., the original having the inclination amount of zero or substantially zero) in accordance with the detection result performed in step S302 . If affirmative determination is made, the process proceeds to step S304, and if negative determination is made, the process proceeds to step S305.

In step S304, the slope correction process is performed on the document determined to be capable of correction, or the slope correction process is not performed on the document determined to be unnecessary, and the document is then recorded in the recording unit 107 Printing). In this case, the image data of the original is individually recorded on the recording medium. When it is designated by the operation unit 104 to copy at the same magnification, an image is recorded on a recording medium having a size corresponding to the size of the original. When the size of the recording medium is designated or the magnification is designated, magnification change processing of the image data is performed before recording the image.

In step S305, it is determined whether there is an image that can not be subjected to the skew correction processing, that is, an image of the original that has not been printed in step S304. If the affirmative determination is made, the process proceeds to step S306, and if the negative determination is made, the indicated copying process is completed, and the process is terminated. If there is a document that can not detect the angle with respect to the horizontal reference in step S302, the document corresponds to the subject of the positive determination made in step S305.

In step S306, the display unit 105 displays a message asking whether or not printing of an image corresponding to the original that can not be subjected to the tilt correction process is performed, as shown in Fig. 4A. When the original that can not be subjected to the inclination correction processing is included in the read original, the user sees the number and content of the image corresponding to the original printed in step S304, and the image of the original which can not be subjected to the tilt correction processing . Therefore, the user can specify the document without opening the document cover.

Thereafter, in step S307, if the user selects to print through the operation unit 104 in response to the inquiry in step S306, the process proceeds to step S308, and in step S307, the user performs printing If not selected, the process ends here.

In step S308, an image corresponding to the original that can not be subjected to the tilt correction processing is recorded on the recording medium using the recording unit 107. [ After all the images of the original that can not be subjected to the tilt correction process are recorded, this flow ends. Here, the image of the original determined by the CPU 101 that can not be subjected to the tilt correction process is recorded in accordance with the determination made by the user, and the image of the original which causes erroneous detection due to the content of the image can also be recorded. Specifically, when the original containing the image inclined obliquely to the white background is read by the reading unit 106, it is easy for the CPU 101 to determine that the original is tilted more than a predetermined tilt amount. When the user recognizes that the document is such a document, or when the user desires to intentionally print the document tilted intentionally, the document is printed without change by selecting printing in step S307.

The content of the inquiry to be displayed on the display unit 105 in step S306 is not limited to the contents shown in Fig. 4A. For example, the screen shown in Fig. 4B may be displayed, so that the user can easily specify a document that can not be subjected to the tilt correction process. The screen shown in Fig. 4B shows that the tilt correction process can not be performed on one of the originals set on the upper right side of the original glass (the original C shown in Fig. 2). Here, since the display mode is changed and four originals are read, the upper right region of the original glass divided into four regions can be distinguished. When two originals are read, the original glass divided into two regions is displayed on the screen.

In the example described above, when the target document that can not be subjected to the inclination correction processing is included in the document, the image of the document that the user can appropriately print, or the position of the target document placed on the document table, . In the following example, an image which can not be subjected to the tilt correction processing among the documents read by the reading unit 106 is displayed on the display unit 105, and the user confirms the document which can not be subjected to the tilt correction processing.

Fig. 5 is a flowchart showing a process performed in this case. This flowchart also shows the flow of processing performed when the CPU 101 loads a program stored in the ROM 102 into the DRAM 103 and executes the program, as in the case of Fig.

The operations in steps S501 to S505 are the same as those in steps S301 to S305, and therefore, the description thereof will be omitted. In step S506, the display unit 105 makes a display to inquire whether it is necessary to execute preview of an image corresponding to the original that can not be subjected to the inclination correction processing. Then, in step S507, it is determined whether or not the user has selected to preview using the operation unit 104. [ If affirmative determination is made, the process proceeds to step S508, and if negative determination is made, the process proceeds to step S509.

In step S508, among the originals read by the reading unit 106 in step S501, the originals determined to be unable to perform the tilt correction processing are displayed on the display unit 105. [ In this case, the magnification processing of the read image data is performed in accordance with the size, resolution, and the like of the display unit 105. The position of the rectangular area set at the time of reading the image of the original by the reading unit 106 is displayed in a distinguishable manner. When the tilt correction process can not be performed for a plurality of originals, the originals to be previewed are successively switched in response to an instruction from the operation unit 104. [

Thereafter, the preview of the image of the original which can not be subjected to the tilt correction processing is terminated. In step S509, the display unit 105 determines whether or not printing of the image of the original which can not be tilt- To be displayed. The operations in steps S509 to S511 are the same as those in steps S306 to S308, and therefore, the description thereof will be omitted.

As described above, according to the processing shown in Fig. 5, after the image of the original which can not be subjected to the tilt correction processing is previewed, the user can also determine whether or not printing of the original that can not be subjected to the tilt correction processing is necessary. Therefore, the user can determine whether or not printing is necessary after the printing state of the image of the original that can not be subjected to the skew correction processing is confirmed.

In the example shown in Fig. 5, after previewing is performed in step S508, in step S509, it is inquired as to whether or not printing of a document that can not be subjected to tilt correction is necessary. In accordance with the response to the inquiry, it is determined whether or not printing of the original that can not be subjected to the inclination correction processing is necessary. However, when there are a plurality of originals for which the tilt correction process can not be performed, the user may desire to determine the necessity of printing for each original. Therefore, when there are a plurality of originals for which the inclination correction processing can not be performed, each time one original is previewed, it is inquired as to whether or not printing is required in step S509, and the original to be printed . In this way, among the originals for which the inclination correction processing can not be performed, the original specified by the user can be selectively printed. It is also possible to preview a document that can be subjected to a tilt correction process or a document that does not require a tilt correction process.

In the case where a document that can not be subjected to the tilt correction process is included, the process may be terminated without printing any document image. For example, the process may be terminated when a negative determination is made in step S507.

In the above-described example, even when a document that can be subjected to a tilt correction process or a document that does not require a tilt correction process is included, even if a document that can not be subjected to the tilt correction process is included (at step S304 or step S504) . However, in the case where the tilt correction process can not be performed on at least one of the originals (or there is a possibility that the tilt correction process can not be performed on at least one of the originals), some users may not want to print one original have. In the following example, when an original that can not be subjected to the inclination correction processing is included, printing is performed after confirming the user's intention.

Fig. 6 is a flowchart showing a process performed in this case. This flowchart also shows the flow of processing performed when the CPU 101 loads a program stored in the ROM 102 into the DRAM 103 and executes the program, as in the case of Fig.

The operations in steps S601 to S603 are the same as those in steps S301 to S303, and therefore, the description thereof will be omitted. If it is determined in step S603 that an original that can not be subjected to the inclination correction process is included, the process proceeds to step S605; otherwise, the process proceeds to step S604.

In step S604, the original is read from the recording unit 107 without performing the inclination correction process on the image data corresponding to the original capable of performing the inclination correction processing or the inclination correction process on the image data corresponding to the original not requiring the inclination correction process, Lt; / RTI > Here, the recording of the image data of all the originals is performed by the recording unit 107, and when the recording performed by the recording unit 107 of all the originals is finished, the processing flow ends here.

In step S605, the display unit 105 displays a message asking whether printing is necessary, as shown in Fig. 4A or Fig. 4B. Thereafter, in response to this inquiry, in step S606, if it is determined by the user that printing via the operation unit 104 has been selected, the process proceeds to step S607, where it is determined that the user has not selected to print If so, the process ends here.

In step S607, the original is recorded on the recording unit 107 without performing the tilt correction process on the image data corresponding to the original capable of tilt correction or the tilt correction process on the image data corresponding to the original not requiring the tilt correction process, Lt; / RTI > In step S608, an image corresponding to the original that can not be subjected to the tilt correction processing is recorded on the recording medium by using the recording unit 107. [ The operations in steps S607 and S608 may be performed in the reverse order. When the operation in step S607 is performed before the operation in step S608, a notification indicating that the original subjected to the tilt correction processing or the original not requiring the tilt correction processing is displayed on the display unit 105 is displayed, and thereafter, the tilt correction is performed A notification indicating that the original can not be printed is displayed so that the user can stop printing. More specifically, even if the user erroneously selects printing in step S606, the user also sees the printed original in step S607 and determines that the subsequent printing (printing in step S608) is unnecessary , Unnecessary printing can be stopped using the operation unit 104. [

As described above, according to the processing shown in Fig. 6, it is possible to determine whether or not printing is necessary before the printing when the original that can not be subjected to the inclination correction is included. Therefore, it is possible to prevent unnecessary printing from being performed unintentionally.

In the process shown in Fig. 6, the preview may be performed as in the process shown in Fig. In this case, between the operations in steps S603 and S605, the preview process described with reference to Fig. 5 may be performed to determine whether or not printing is necessary.

As described above, according to the present embodiment, even when a slope correction process is performed on a part of a plurality of originals and the original is separately processed, even if the original is not capable of performing the slope correction process, . According to the example described with reference to Fig. 3 and Fig. 5, the image of the original properly read out is printed first, except for the image of the original which can not be subjected to the tilt correction process. Then, the original which can not be subjected to the tilt correction process is reset, and the original is read and printed. Therefore, since the document is reset until all the documents are appropriately set, it is possible to prevent the operation from being delayed when the properly read document is tilted. Further, according to the example described with reference to Fig. 6, printing is performed when all originals are appropriately read, thereby preventing unwanted printing from being performed. Although an example of the process performed when the original that can not be subjected to the inclination correction process is included is described above, one of the processes to be performed when it is determined that the original that can not be subjected to the inclination correction is included in the operation unit 104, and the processing is performed in accordance with the selection.

In the above description, the multifunction apparatus including the reading unit 106 and the recording unit 107 is described as an example. However, the processing of the present embodiment can also be performed in an apparatus other than the multifunction apparatus having such a configuration. (Scanner) and a recording apparatus (printer) may be connected to a general-purpose personal computer (PC), or a program (software) used for executing processing of the present embodiment may be installed in a PC, It can be operated simultaneously. In addition, the processing of the present embodiment may be executed by a scanner connectable to an external printer (which performs printing in response to an instruction supplied from a scanner). Further, the process of the present embodiment may be executed by a printer connectable to an external scanner (which performs reading under the control of the printer).

Further, in the above description, the image of the original placed on the original table is read by the reading apparatus. However, the present invention is not limited to this, and the original may be sandwiched between transparent films, and the inserted original may be read by the reading device while being conveyed by the automatic document conveying device.

In the above description, a reading apparatus that reads an image on a document table and serves as an input source of an image of a document, and a recording apparatus that serves as an output destination of image data that prints an image and displays an image of the document . However, the present invention is not limited thereto. As an input source of the image of the original, a digital camera, image processing application software installed in the PC, or the like may be employed. In this case, the image data is input from the input source in page units, and the reading performed by the reading unit 106 is replaced with the input of the image data representing the image of the original. Specifically, each page corresponds to each original. In the case where the concept of "page" is not suitable for the input source, "file unit" is employed instead of "page unit ". That is, one file corresponds to one original. As an output destination, transmission to an external device or storage in an external storage device may be employed instead of the recording device. In this case, at the time of outputting the image data, the image data corresponding to the plurality of pages is output in a unit of page. For example, the output image data is displayed in page units in the application software operating in the external apparatus. In this case, the image data corresponding to the slope-correctable document is displayed in a corrected state. The process of separately outputting image data corresponding to a plurality of pages includes transmitting image data corresponding to a plurality of pages as different files or performing storage. As the transmission method, it is also possible to employ an electronic mail transmission in which image data corresponding to a plurality of pages is formed as different image files serving as an attachment file. Examples of transmission methods include FTP transmission, SMB transmission, and WebDAV transmission in addition to e-mail transmission. Further, when the image processing apparatus is connected to an external apparatus via a local I / F such as a USB I / F, image data corresponding to a plurality of pages is transmitted to the external apparatus according to the USB protocol. Examples of the external storage device include a removable memory card or a portable memory medium such as a USB memory and a storage device externally connected via a cable.

In the case where the digital camera serves as the input source of the original, the tilt correction process as described above is performed on the image obtained when the camera is tilted at the time of photographing. In addition, when the application software serves as an input source of the original, the application software acquires the tilted image, and then performs the tilt correction process as described above.

The above embodiment can also be realized by executing the following processing. Specifically, a software (program) for realizing the functions of the above-described embodiments is supplied to a system or an apparatus via a network or various storage media, and a computer (or a CPU or MPU) of the system or apparatus reads and executes the program do.
